How Soon After Applying Fertilizer Can I Plant Grass Seed?

When Can You Plant Grass Seed After Applying Fertilizer?

Planting grass seed can be a frustrating process because of the wait time. Plant grass seed too early and it may not have enough time to grow before winter comes around. Plant grass seed too late and it can’t grow at all until the following year. I found that this process can be accelerated with the application of fertilizer. After much trial and error, I was able to determine the best time to plant grass seed!

How soon after applying fertilizer can I plant grass seed? If you apply fertilizer and then plant grass seed at least four weeks after, the grass seed will grow significantly faster than it would without fertilizer. This is because the grass seed will use the fertilizer to build more roots, which then grow into new grass.

Although fertilizer can make a huge difference in how successful your plant can grow, it also depends on multiple variables to maintain its growth. I will discuss how important each factor is when growing grass in your yard!

At What Time Should I Plant Grass Seed?

I recommend planting grass seed around early to mid-September. Planting too early can make your plants susceptible to frost. However, planting too late may not have enough time to allow your grass seed to grow before winter. Planting in the middle of September is a good idea because it gives the grass time to grow and establishes roots that can survive through winter!

Avoid planting grass seed in the early spring – planting grass in the early spring is not the best idea because it will not be able to successfully grow before winter. Planting grass in the late fall is also a bad idea because frost will kill off any plants that are just beginning to grow!

Apply enough fertilizer, but not too much! Plant grass seed is particularly susceptible to being burned by fertilizer. If you are using a fertilizer with chemical components, it will most likely burn the young plants because they are not as strong or hardy as older plants.

I recommend using organic fertilizers, which have nutrients that are easier for the root systems of grass seedlings to absorb. Plant grass seed fertilizer is great because it allows the grass to absorb nutrients at a steady rate.

Fertilizing can be tricky, so I recommend using a ratio of 100lbs nitrogen per acre for every month that you have to wait after applying the fertilizer. This means that if you have waited four weeks, then apply 400lbs of nitrogen per acre. You can buy grass seed fertilizer or you can mix your fertilizer with water if you have the time and energy!

While Planting Grass Seed, What Soil Should I Use?

For fantastic results, use potting soil rather than regular dirt. Regular dirt does not have enough nutrition for quick grass growth (making your wait even longer), but potting soil has exactly what your grass needs to establish roots and start growing! Potting soil will make all the difference in the success of growing grass outside your home!

By following this process, your grass seed can grow much faster than it would without fertilizer. Planting grass seed with fertilizer is the best choice to make sure that grass grows fast enough before winter comes around. Plant your grass as early as you can for best results and enjoy a happy yard filled with green throughout the fall and winter!

At this point, I recommend not doing anything for one month after planting grass seed! If you fertilize the area immediately after planting the grass seed, then it can burn the grass. Allow the grass to establish roots by leaving it alone for at least one month, although I would recommend waiting two months before you start walking on the grass.

After two months have passed after planting grass seed, fertilize it once more with nitrogen fertilizer. For example, if you are using 100lbs of nitrogen per acre every month, then apply 200lbs of nitrogen in the second month that you wait after planting grass seed! If you live in a colder environment where winter is around the corner, then also use an organic fertilizer with some extra nutrition to help your grass grow during this harsh time of year.

Should I Fertilize or Seed My Lawn First?

If your grass is more of a brown color, then it needs to be seeded rather than fertilized. Fertilizing grass that is already dead will not help the grass grow more because it does not have any nutrients. Planting grass seed after seeding the area can get weeds mixed in with your new plants if you are not careful!

How Can I Make Grass Seed Grow Faster?

There are many different things that you can do to make grass seed grow faster. Planting the grass seed in the right type of soil is very important, as well as planting it at the right time of year. During the spring and summer seasons, grass seed grows much faster than during the winter. Planting seeds underneath a grow lamp will also help it to grow faster.

Planting grass seed directly into the ground is best, but if your grass is not full enough then you can use a lawnmower on it too.

Another way that you can make grass seed grow faster is by sprinkling it with water every other day; this will help to saturate the soil and enable the seeds to grow at their maximum potential. Planting grass seed during times of the year when there are more hours of sunlight also helps them to grow faster.

Planting grass seed in areas where there isn’t already any type of vegetation will help make it grow faster because the soil hasn’t yet been occupied and drained of its nutrients.

What Are the Benefits of Soaking Grass Seed Before Planting?

Soaking grass seed before you plant it can have many benefits. The grass will grow uniformly because all grass seeds are at the same stage of growth when they are planted after being soaked in water. This is much different than planting grass seeds that have not been soaked, where some grasses are beginning to sprout while others are still in dormant stages.

Knowing when grass seeds have been soaked enough is crucial to the grass growing at its optimal rate. The grass will reach a stage in its growth when it can be planted, and you should never plant grass seed before or after this point because it will not grow properly if you do so.

One method for determining this point in time is by slightly tugging on grass seed: if it seems very loose in your hand then it could be too early to plant; if the grass seed does not budge at all, however, then it may already be too late.

The most important thing that you need to know about soaking grass seeds is that if they are left unattended for too long, grass seeds can absorb too much water and rot. You should always use an equal amount of grass seed and water when soaking grass seed, you want to make sure that all grass seeds are getting equal attention so that there isn’t one root system that is doing significantly better than another.

You can soak grass seed in a bowl or bucket with water for up to 24 hours without any significant harm done to the grass. If you are soaking grass seed overnight then it is recommended that you change out the water every 8 hours. Make sure that the grass seed gets plenty of oxygen while they are being soaked because this will enable them to grow better after planting.

When you plant grass seed, you must give each one its fair chance to grow. This means that you shouldn’t plant grass seed too densely or too sparsely; if grass seeds are planted more than 2 inches apart then the grass will be thin, and if grass seeds are planted less than 1/2 of an inch apart they will crowd each other and not grow correctly.

When grass seed is soaked before planting it will grow much faster. Soaking grass seed is one of the easiest ways to get grass to grow, but it’s also important that you plant grass seeds in the right season and soil type for them to have the best possible chance of success.


In conclusion, grass seed benefits from fertilizer. The grass seed benefits from the fertilizer because it increases the grass yield when applied to grass seeds in six weeks before planting them in grass fields. Fertilizer is beneficial because it creates stronger grassroots and provides more support for the growing grass.

Be sure to follow the directions when using fertilizer on grass seed because if you use too much, it can burn the grass seed! Once you can achieve healthy germination, your grass will begin to grow healthy and beautiful!
